At a school the ratio of boys to girls is 11 : 9
there are 124 more boys than girls.
work out the total number of students at the school.

1240

Step-by-step explanation:

Total boys : Total Girls

= 11x  : 9x

9x + 124 = 11x

124 = 2x

x = 62

11x = 11 x 62 = 682

9x = 9 x 62 = 558

Total number of students = 682 + 558 = 1240

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.

30,40,50 is correct answer
